CVE-2022-35873
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThis vulnerability allows remote attackers to execute arbitrary code on affected installations of Inductive Automation Ignition 8.1.15 (b2022030114). User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of ZIP files. Crafted data in a ZIP file can cause the application to execute arbitrary Python scripts. The user interface fails to provide sufficient indication of the hazard. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-16949.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis vulnerability in Inductive Automation Ignition 8.1.15 allows remote code execution through malicious ZIP files containing crafted Python scripts. The application processes ZIP archives without proper validation of contents, enabling arbitrary Python script execution when a user opens a malicious file. The vulnerability executes in SYSTEM context.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Ignition versionCheck the installed Inductive Automation Ignition version through the Gateway status page, About section, or by inspecting the installation manifest. On Windows, this is typically found in the Gateway under Status > Gateway > About, or check the install directory for version files.Affected if The installed version is exactly 8.1.15
-
Confirm ZIP file processing is accessibleIdentify if users or automated processes can submit ZIP files to the Ignition Gateway. This includes checking for any projects, scripts, or modules that accept archive uploads, particularly through the Designer, Perspective, or Gateway webhook endpoints.Affected if The Gateway accepts or processes ZIP archive uploads from users without content validation enabled
-
Review recent ZIP file importsExamine Gateway logs, script execution logs, and project import history for any recent ZIP file imports. Check logs for entries containing 'ZIP', 'archive', 'import', or Python script execution patterns.Affected if There are recent records of ZIP file imports or archive processing in the logs
-
Assess system exposureDetermine if the Ignition Gateway is accessible over the network to external users or if it processes files from untrusted sources. Check firewall rules and authentication requirements for any endpoints that handle file uploads.Affected if The Gateway is network-accessible to untrusted users or accepts files from external/untested sources
A system is affected if it runs Ignition version 8.1.15 and processes ZIP archives from users or external sources without validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict handling of untrusted ZIP files until vendor patch is applied; implement file content validation and sandboxing for archive processing; train users to avoid opening untrusted files given the required user interaction.
